[0010] FIGS. 1 to 3 illustrate a display device 10. In FIG. 2, the
display device 10 comprises a cover 100, a frame 200, a liquid
crystal display (LCD) 300, a touch panel 400, and a bracket 500.
The touch panel 400, the liquid crystal display (LCD) 300, the
bracket 500, the frame 200, and the cover 100 are attached together
in that order.
[0011] In the exemplary embodiment, the cover 100 is a cuboid, and
is made of metal (such as iron) or metal alloy. A plurality of
through holes 110 are defined in the cover 100. The through holes
110 pass through the cover 100. In the exemplary embodiment, the
number of the through holes 110 is two. The two through holes 110
are formed on opposite edges of cover 100. A groove 120 is defined
at a center of a surface of the cover 100. The groove 120 is cuboid
in shape. The two through holes 110 are located at a bottom surface
of the groove 120 and near opposite sidewalls of the groove 120.
The cover 100 further defines an opening 130 adjacent to the groove
120 and passing through the cover 100. The opening 130 and the
groove 120 form an interconnecting sidewall 140 therebetween.
[0012] The frame 200 comprises an upper surface 210 and a lower
surface 220. The upper surface 210 and the lower surface 220 are
opposite surfaces of the frame 200. The lower surface 220 faces the
cover 100. The upper surface 210 faces away from the cover 100. A
plurality of first screw holes 230 are defined in frame 200, and
pass through the upper surface 210 and the lower surface 220. Two
of the first screw holes 230 correspond to the two through holes
110, respectively. In the exemplary embodiment, a cylindrical
flange 232 protrudes from the lower surface 220 and is formed
around each first screw hole 230. The outer diameter of the
cylindrical bulge 232 is less than or equal to the diameter of the
two through holes 110. The frame 200 and the cover 100 are aligned
and assembled by two cylindrical bulges 232 and two through holes
110.
[0013] The LCD 300 comprises a front surface 310 and a rear surface
320. The front surface 310 and the rear surface 320 are opposite
surfaces of the LCD 300. The front surface 310 is parallel to the
rear surface 320. The rear surface 320 faces the upper surface 210.
The front surface 310 faces away from the upper surface 210.
[0014] A plurality of screw studs 330 is on the rear surface 320.
The screw studs 330 and the LCD 300 are integrally formed. The
screw studs 330 correspond to the first screw holes 230. Two of the
screw studs 330 correspond to two of the first screw holes 230 and
to two of the through holes 110. Referring to FIG. 3, the screw
stud 330 comprises a base 332 and a cylindrical portion 334. The
base 332 is mounted on the rear surface 320. The cylindrical
portion 334 is at the center area of the base 332. In the exemplary
embodiment, the cylindrical portion 334 is a hollow cylinder. The
cylindrical portion 334 comprises a first member 336 on the base
332 and a second member 338. A lower portion of the first member
336 is surrounded by the second member 338. Both the first member
336 and the second member 338 form the cylindrical portion 334. A
second screw hole 3360 is defined in the first member 336. The
height of the second member 338 is less than the height of the
first member 336. The outer diameter of the second member 338 is
smaller than the diameter of the first screw hole 230. The
cylindrical portion 334 can extend to the first screw hole 230. In
the exemplary embodiment, the base 332 is on the rear surface 320.
The base 332 is parallel to the rear surface 320.
[0015] In the exemplary embodiment as shown in FIG. 2, the touch
panel 400 is a cuboid. The size of the touch panel 400 is
substantially the same as the size of the frame 200. The touch
panel 400 comprises a first surface 410 and a second surface 420.
The first surface 410 and the second surface 420 are opposite
surfaces of the touch panel 400. The first surface 410 is parallel
to the second surface 420. The first surface 410 faces the front
surface 310. The second surface 420 faces away from the front
surface 310. The first surface 410 comprises a display area 412 and
a non-display area 414. The display area 412 is surrounded by the
non-display area 414. A size of the display area 412 is equal to a
size of the LCD 300. The display area 412 is electrically connected
to the LCD 300. The non-display area 414 is connected to the edge
of the upper surface 210.
[0016] The bracket 500 comprises a clamping portion 520 and a
protruding portion 510 extending from the clamping portion 520. The
clamping portion 520 wraps around the rear surface 320 and one side
of the LCD 300. The protruding portion 510 comprises a connecting
portion 5101 and a free end 5102. The connecting portion 5101 is
perpendicular to the rear surface 320. The free end 5102
perpendicularly extends from the connecting portion 5101 and is
parallel to the rear surface 320. The connecting portion 5101
passes through the opening 130, so that the free end 5102 is
exposed from the cover 100 and resists the interconnecting sidewall
140. The protruding portion 510 is used to further clamp the cover
100 and the frame 200 together.
[0017] The display device 10 further comprises a plurality of screw
bolts 600. The screw bolts 600 are engaged with the second screw
holes 3360 to assemble the display device 10. Each screw bolts 600
comprises a screw arbor 610 and a nut 620. The nut 620 is at one
end of the screw arbor 610. Two of the screw arbors 610 pass
through two of the through holes 110 and two corresponding first
screw holes 230, and are received in two corresponding second screw
holes 3360. The nuts 620 resist the top surface of the first
members 336 of the cylindrical portions 334. The height of the
second member 338 being different from the first member 336 renders
it convenient to disassemble the screws bolt 600 from the second
screw hole 3360.
[0018] In assembly, a double-sided adhesive tape (not shown) is
first adhered to the non-display area 414. Then, the LCD 300 is
aligned with the displayed area 412 and placed on the display area
412. The peripheral edges of the frame 200 are bonded to the
non-display area 414 by the double-sided adhesive tape. The frame
200 is further fastened to the LCD 300 through the screw bolts 600
and the screw stud 330, thereby mounting the LCD 300 between the
frame 300 and the touch panel 400. The cover 100 covers the frame
200, with the screw studs 330 being aligned with two through holes
110 and passing through the through holes 110. Then, the cover 100
is mounted to the frame 200 by the screw bolts 600, so that the
frame 200 and the LCD 300 are between the cover 100 and the touch
panel 400. The protruding portion 510 further clamps the cover 100
and the frame 200 together.
[0019] With the above configuration, the display device 10 includes
the screw studs 330 on the rear surface 320, and the first screw
holes 230 are defined in the frame 200. The screw studs 330 can be
engaged with the first screw hole 230 to assemble the LCD 300 and
the frame 200 together. Thus, connection strength, shock proofing
and vibration proofing between the LCD 300 and the frame 200 are
improved.
[0020] The exemplary embodiments shown and described above are only
examples. Even though numerous characteristics and advantages of
the present technology have been set forth in the foregoing
description, together with details of the structure and function of
the present disclosure, the disclosure is illustrative only, and
changes may be made in the detail, including in matters of shape,
size, and arrangement of the parts within the principles of the
present disclosure, up to and including, the full extent
established by the broad general meaning of the terms used in the
claims.
